Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly relates to a charging device and an assembly method thereof. Background Art

[0002] At present, the mainstream air purification technologies are divided into media filtration technology and electrostatic purification technology.

[0003] The media filtration technology is mature and operates relatively stably, but it has high air resistance, high fan energy consumption, is prone to breed bacteria and viruses, cannot sterilize and disinfect, has peculiar smell, needs to be replaced frequently, generates a large amount of consumables, has high operation and maintenance costs, and is not energy-saving and environmentally friendly.

[0004] The electrostatic purification technology can remove particulate matter, sterilize and disinfect, has low resistance, and can be washed repeatedly. However, due to its low purification efficiency, relatively high power, easy to generate sparks, high ozone content, poor safety, short service life, large weight, and high maintenance cost, it is not energy-saving and environmentally friendly. As a result, it cannot be widely applied in the field of light pollution air purification and can only be used in very few scenarios.

[0005] The micro-electrostatic technology combines the advantages of the media filtration technology and the electrostatic purification technology, taking into account high-efficiency purification and dust removal, sterilization and disinfection, as well as having technical advantages such as ultra-low power, low resistance, high humidity resistance, high safety, can be washed repeatedly, no consumables, and a service life of up to 10 years.

[0006] Currently, the discharge needles in the charging devices on the market are arranged facing the wind and are perpendicular to the micro-electrostatic filter element. Such a structural method cannot make full and effective use of the size in the thickness direction of the purification device. It occupies a relatively large size in the thickness direction. When it is installed and used in conjunction with air-conditioning equipment in places where the thickness dimension is limited, it often cannot be adapted due to size problems, or the dust collection device in the second section is made thinner, sacrificing the purification ability of the dust collection device for compromise use; at the same time, due to the relatively complex production of the ionization structure, the overall cost is relatively high; and the tip of the discharge needle has a sharp angle, and care needs to be taken to avoid being damaged during production, installation, transportation, and maintenance.

[0007] Based on this, the prior art needs to be further developed. Summary of the Invention

[0008] The purpose of the present invention is to overcome the above technical deficiencies and provide a charging device and an assembly method thereof to solve the technical problem that the charging device in the related art occupies too much installation space.

[0009] To achieve the above technical purpose, the present invention adopts the following technical solutions:

[0016] This technical solution is further configured such that the electrode body is connected to a high-voltage power supply, and the high-voltage power supply is an internal high-voltage power supply or an external high-voltage power supply.

[0017] This technical solution is further configured such that a second receiving groove for accommodating the electrode heads is fixedly provided on the outer side of the groove wall of the first receiving groove, and the second receiving grooves are provided in one-to-one correspondence with the electrode heads.

[0018] This technical solution is further configured such that the first receiving groove is detachably connected to the interior of the frame body, and both ends of the first receiving groove are provided with notches matching the frame body. When the first receiving groove is installed inside the frame body, the first receiving groove does not protrude beyond the outer surface of the frame body.

[0019] This technical solution is further configured such that the electrode heads are carbon fiber brushes, or bundled metal wires, or metal tips.

[0020] This technical solution is further configured such that the housing has a first frame and a second frame, and the first frame and the second frame are complementary structures that can be spliced.

[0021] This technical solution is further configured such that a discharge conductor is provided on the housing, and a discharge conduction hole matching the electrode head is formed on the discharge conductor.

When using flexible electrode heads such as carbon fiber brushes, the humanization is more guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0050] According to an embodiment of the present invention, a charging device is provided. Please refer to Figures 1 to 3 , including: a housing 1; a first receiving groove 2, the first receiving groove 2 is arranged inside the housing 1; an electrode body 3, the electrode body 3 is arranged in the first receiving groove 2 and arranged along the length direction of the first receiving groove 2; an electrode head 4, the electrode head 4 penetrates through the groove wall of the first receiving groove 2 and is connected to the electrode body 3, and a plurality of electrode heads 4 are arranged at intervals along the electrode body 3 so that the discharge area covers the entire inside of the housing 1; the electrode body 3 and the connector for connecting the electrode head 4 and the electrode body 3 are both sealed in the first receiving groove 2.

[0051] It should be noted that the first receiving groove 2 for accommodating the electrode body 3 is arranged inside the housing 1, which reduces the space occupied by the charging device in the thickness direction. At the same time, a new charging and discharging form is adopted, and the electrode heads 4 are evenly arranged, so that the discharging is more sufficient, there is no charging blind area, the charging uniformity of the particulate matter is better, and the charging effect is better.

[0052] Specifically, the electrode head 4 is a carbon fiber brush, or a bundle of metal wires, or a metal tip. The first receiving groove 2 is made of an insulating material, and the electrode body 3 and the connector for connecting the electrode head 4 and the electrode body 3 are sealed in the first receiving groove 2 by an insulating sealant. The carbon fiber brush includes a plurality of bundles of carbon fiber filaments, an insulating tube, and is electrically connected to the electrode body 3 through a conductive metal wire.

[0053] In the charging device of this embodiment, a plurality of first receiving grooves 2 are provided, and the plurality of first receiving grooves 2 are arranged at intervals, and the electrode bodies 3 in different first receiving grooves 2 are connected end to end in sequence to form an S-shaped bend.

[0054] Specifically, the plurality of electrode bodies 3 in different first receiving grooves 2 can be electrically connected through a conductive wire 31 or by other means.

[0055] In the charging device of this embodiment, please refer to Figure 4 , on the outer side of the groove wall of the first receiving groove 2, a second receiving groove 5 for receiving the electrode head 4 is fixedly provided, and the second receiving grooves 5 are arranged in one-to-one correspondence with the electrode heads 4.

[0056] It should be noted that the second receiving groove 5 is used to support the electrode head 4 to prevent the electrode head 4 from shifting due to bumping.

[0057] In the charging device of this embodiment, the included angle formed by the arrangement direction of the electrode head 4 and the plane where the frame 1 is located is greater than or equal to 0 degree and less than or equal to 60 degrees, so as to further reduce the thickness of the charging device. Both sides of the first receiving groove 2 are connected with the electrode heads 4, and the distance between two adjacent electrode heads 4 on the same side of the same first receiving groove 2 is equal to the distance between two adjacent first receiving grooves 2.

[0058] It should be noted that the included angle range between the arrangement direction of the electrode head 4 and the plane where the frame 1 is located is from 0 degree to 60 degrees, and it is not arranged facing the wind. In the links of production, transportation, installation and maintenance, it is not easy to contact or bump the tip of the electrode head 4. When the electrode head 4 is made of a hard material such as a metal tip, the electrode head 4 does not protrude beyond the outer surface of the frame 1 to reduce the installation space occupied by the charging device; when the electrode head 4 is made of a flexible material such as a carbon fiber brush, the electrode head 4 can protrude beyond the outer surface of the frame 1. Preferably, the length of the electrode head 4 protruding beyond the outer surface of the frame 1 does not exceed 50% of the total length of the flexible material. By using the flexibility of the flexible material, when the charging device is installed in a restricted space, it can smoothly pass through the restricted installation part. After being installed in place, due to the self-recoverability of the flexible material and the fact that the front end of the electrode head 4 is an open space not less than the thickness space of the frame 1 after installation, the flexible material can automatically return to its original state, so as to increase the included angle between the arrangement direction of the electrode head 4 and the plane where the frame 1 is located as much as possible, and the flexible material is not likely to cause accidental injury to the staff. From the perspective of the charging principle, the larger the included angle, the better the charging effect.

[0059] It is worth mentioning that when the angle between the arrangement direction of the electrode head 4 and the plane where the frame body 1 is located is greater than 60 degrees, it can be used in scenarios with a relatively large installation space. For example, when the arrangement direction of the electrode head 4 is perpendicular to the plane where the frame body 1 is located and a flexible electrode head material, such as a carbon fiber brush, is adopted, the electrode head 4 can extend beyond the outer surface of the frame body 1 by a certain distance. Preferably, the length by which the electrode head 4 extends beyond the outer surface of the frame body 1 does not exceed 50% of the total length of the flexible material. By utilizing the flexible characteristics of the carbon fiber brush, it can smoothly pass through the restricted installation area. After being installed in place, due to the self-recoverability of the flexible material, the flexible material can automatically return to its original state. Similarly, it can also improve the utilization rate of the installation space, achieve the same ionization effect, make the ionization device thinner, and have a wider application range.

[0060] In the charging device of this embodiment, please refer to Figure 5 , the angle formed by the arrangement direction of the electrode head 4 and the plane where the frame body 1 is located is 0 degrees, that is, the arrangement direction of the electrode head 4 is parallel to the plane where the frame body 1 is located, which is more convenient for production and processing, and the charging effect meets the use requirements of the charging device. Both sides of the first receiving groove 2 are connected with the electrode head 4, and the distance between two adjacent electrode heads 4 on the same side of the same first receiving groove 2 is equal to the distance between two adjacent first receiving grooves 2; the electrode heads 4 on both sides of the same first receiving groove 2 are arranged side by side to form a plurality of electrode pairs, and the electrode pairs located in different first receiving grooves 2 are arranged in a matrix. This is the electrode head arrangement method 1.

[0061] In the charging device of this embodiment, please refer to Figure 6 , the angle formed by the arrangement direction of the electrode head 4 and the plane where the frame body 1 is located is 0 degrees, both sides of the first receiving groove 2 are connected with the electrode head 4, and the distance between two adjacent electrode heads 4 on the same side of the same first receiving groove 2 is equal to the distance between two adjacent first receiving grooves 2; the electrode heads 4 on both sides of the same first receiving groove 2 are arranged side by side to form a plurality of electrode pairs, and the electrode pairs located in different first receiving grooves 2 are arranged staggeredly. This is the electrode head arrangement method 2.

[0062] It should be noted that the electrode pairs are arranged staggeredly, and the discharge areas formed by the electrode heads 4 on the opposite sides of two adjacent first receiving grooves 2 partially overlap, and it can effectively ensure that the discharge area completely covers the entire frame body 1.

[0063] In the charging device of this embodiment, please refer to Figure 7, the included angle formed by the arrangement direction of the electrode head 4 and the plane where the housing 1 is located is 0 degree. Both sides of the first receiving groove 2 are connected with the electrode head 4, and the distance between two adjacent electrode heads 4 on the same side of the same first receiving groove 2 is equal to the distance between two adjacent first receiving grooves 2; the electrode heads 4 on both sides of the same first receiving groove 2 are arranged staggeredly, and the arrangement of the electrode heads 4 on several first receiving grooves 2 is the same. This is the electrode head arrangement method 3.

[0064] In order to verify the performance differences of the three electrode head 4 arrangement methods, a comparative test was conducted in a standard laboratory. The same micro-electrostatic module was adopted (the micro-electrostatic module forms an electrode plate by wrapping a conductive material with a dielectric material, and uses the strong electric field between the electrode plates to capture charged particulate matters in the air), and then three kinds of charging devices were matched. The PM2.5 purification efficiency of the carbon fiber brush electrode head 4 was compared under the same working environment and the same wind speed. In order to reduce the test error, the PM2.5 purification efficiency was compared by taking the average value of three groups of continuously tested data.

[0065]

[0066] Through the comparison of the test data, it can be seen that when the three charging devices are matched with the same micro-electrostatic module, they all have a high PM2.5 purification efficiency, which can show that the charging devices of the three electrode head 4 forms all have a good charging effect, and the charging effect: arrangement method 2 > arrangement method 3 > arrangement method 1.

[0067] Preferably, in order to make full use of the discharge area of the electrode head 4, several first receiving grooves 2 are arranged in parallel and at equal distances, and the distance between the first receiving groove 2 on the side and the housing 1 is not greater than 1 / 2 of the distance between two adjacent first receiving grooves 2.

[0068] In the charging device of this embodiment, the electrode body 3 is connected with a high-voltage power supply, and the high-voltage power supply is an internal high-voltage power supply or an external high-voltage power supply.

[0069] Preferably, please refer to Figure 8 , an internal high-voltage power supply is adopted, and a power supply compartment 14 is added on one side of the housing 1, and the high-voltage power supply is placed in the power supply compartment 14. Since the charging device needs to be powered by a high-voltage power supply, when the high-voltage power supply is external, the high-voltage electrode box is exposed to the air for a long time, and due to the dirt of the high-voltage electrode box, the electrode box may creep and arc, thus affecting the discharge efficiency of the electrode head 4, and even causing damage to the charging device or the high-voltage power supply. The internal power supply can improve the reliability of the charging device. The charging device frame is provided with a power connection piece for connecting an external power supply device.

[0070] In the charging device of this embodiment, please refer to Figure 9, the first receiving groove 2 is detachably connected to the interior of the frame 1. The two ends of the first receiving groove 2 are provided with notches 21 that match the frame 1. When the first receiving groove 2 is installed inside the frame 1, the first receiving groove 2 does not extend beyond the outer surface of the frame 1.

[0071] It should be noted that the two ends of the first receiving groove 2 are provided with notches 21 that match the frame 1, so that the two ends of the first receiving groove 2 are exactly embedded in the frame 1. The frame 1 at the position of the notch 21 plays a limiting role on the first receiving groove 2, increasing the stability of the first receiving groove 2. The depth of the notch 21 is less than or equal to the wall thickness of the frame 1, ensuring that the first receiving groove 2 will not extend beyond the frame plane after installation, further saving the installation space of the charging device.

[0072] Preferably, reinforcing ribs are added between adjacent first receiving grooves 2. When the area of the charging device is large, the structural strength and stability are increased through the reinforcing ribs between the first receiving grooves 2.

[0073] In the charging device of this embodiment, the frame 1 has a first frame 12 and a second frame 13. The first frame 12 and the second frame 13 are complementary structures that can be spliced, enabling the rapid splicing of multiple charging devices. The above complementary structure is any splicing structure in the prior art, including a plane mechanism that fits together, etc., and the positions of the first frame 12 and the second frame 13 are not limited.

[0074] In the charging device of this embodiment, please refer to Figure 10 , a discharge conductor 6 is provided on the frame 1, and a discharge conductive hole 61 that matches the electrode head 4 is opened on the discharge conductor 6.

[0075] Specifically, the discharge conductor 6 is made of a metal material or a non-metal material. A plurality of discharge conductive holes 61 are provided, and the plurality of discharge conductive holes 61 are arranged in a rectangular array. The discharge conductive holes 61 are round holes, rectangular holes, or nearly round holes with a curved angle.

[0076] Preferably, each discharge conductive hole 61 is arranged in a rectangle, and rounded corners are formed at the four corners of each discharge conductive hole 61. The rectangular rounded corners have the highest coverage rate, few blind areas, achieve a full coverage of the through-hole area of the discharge conductor 6, uniform oncoming wind speed, and reduced ventilation resistance.

[0077] According to another embodiment of the present invention, an assembly method is provided for assembling the above charging device. When the first receiving groove 2 is detachably connected to the frame 1, the assembly method one is used to assemble the above charging device. The assembly method one includes the following steps:

[0078] Step S11: Arrange a plurality of first receiving grooves 2 at intervals;

[0079] Step S12: Place the electrode body 3 into the first receiving groove 2, and connect the electrode bodies 3 located in different first receiving grooves 2 end to end in sequence to form an S-shaped curve;

[0080] Step S13: Sequentially pass a plurality of electrode heads 4 through the wall of the first receiving groove 2 and connect them to the electrode body 3;

[0081] Step S14: Pour sealant inside the first receiving groove 2;

[0082] Step S15: After the sealant solidifies, install the frame body 1 around a plurality of first receiving grooves 2.

[0083] Specifically, if the charge device is provided with a discharge conductor 6, the first assembly method further includes: Step S16: Install the discharge conductor 6 on the frame body 1, and the discharge conduction holes 61 on the discharge conductor 6 correspond to the positions of the electrode heads 4.

[0084] When the first receiving groove 2 is integrally connected to the frame body 1, use the second assembly method to assemble the above charge device. The second assembly method includes the following steps:

[0085] Step S21: Place the electrode body 3 into the first receiving groove 2;

[0086] Step S22: Sequentially pass a plurality of electrode heads 4 through the wall of the first receiving groove 2 and connect them to the electrode body 3;

[0087] Step S23: Pour sealant inside the first receiving groove 2 until it solidifies.

[0088] Specifically, if the charge device is provided with a discharge conductor 6, the second assembly method further includes: Step S24: Install the discharge conductor 6 on the frame body 1, and the discharge conduction holes 61 on the discharge conductor 6 correspond to the positions of the electrode heads 4.

[0089] The present invention has been described in detail above; the above are only the preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereby. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
